Before you start
For instructions on connecting the SAS tape drive to an external SAS port, see
“Installing an external DAT SAS tape drive” on page 37.
If your server does not have an external SAS port, you can connect the external tape drive to an
internal port on the host controller or new HBA. This configuration may also be useful if the server
does not have a spare, internal half-height bay for an internal tape drive.
There are two connection options:
• Use one of the recommended HP cables to connect the tape drive to a spare internal SAS port on
the host SAS controller or to an internal port on a new HBA.
• Use one of the recommended HP cables to replace one of the existing SAS cables to the hard disk
drive bays. This requires some recabling inside the server, and also disconnects one of the hard
disk drive bays. This configuration is suitable for some HP ProLiant servers only and, if it does
disconnect a hard disk drive bay, you must be sure that the hard disk drive bay is not required
for use. If it is required, install a new HBA.
